<P>If a number of rectangular SMD pads (Pads,paste mask and solder mask) on a equal distance needs to be included, this function can do the job. In the next dialogbox all the necessary parameters can be entered. After pressing the <B>OK</B> button the pads can be placed. When pressing the <B>right mouse button</B> the pads will rotate 90 degrees counter clock wise. By pressing and keep down the <B>shift</B> key and moving the mouse cursor, the moving center will change. When the <B>spacebar</B> is pressed, a dialogbox will popup, and the position of the first pad can be edited by hand. When the first character typed is a <B>@</B> the coordinates will be relative against the <B>Relative (grid)position</B>. The coordinates typed in will be used with the current units (dimension).</P>

<P>The function <B>Add SIL SMD based on selected objects</B> will do the same, but the dialogbox parameters will already be filled, with the parameters of a <B>selected</B> pad.</P>

<P>The following parameters can be changed:</P>

<P><U>Pad width and height</U></P>

<P><U>Pitch</U></P>

<P><U>Nr pads</U></P>

<P><U>Pad width and height solder paste</U></P>

<P>If the solder paste pad is not necessary, fill the X or Y parameter with zero.</P>

<P><U>Pad width and height solder mask</U></P>

<P>If the solder mask pad is not necessary, fill the X or Y parameter with zero.</P>

<P><U>Top/bottom layer</U></P>

<P>The pads will be placed on the top or bottom layer</P>

<P><U>Clearance</U></P>

<P>The initial clearance is the clearance used for this geometry.</P>

<P><U>Startpin</U></P>

<P>The startpin consists of two editboxes. The first editbox(optional) contains text or a number, and will not be changed. The second editbox contains a start number. This startnumber will be increased with <B>Increment</B> for the next pads.</P>

<P>The <B>Use default rules for solder paste/mask and clearance</B> button can be used the fill in values based on the pad size.</P>
